Beit known that I, MORTIMER KINZEY, a

' citizen of the United States,-residing at New?` ark, in the county ofEssex and State of New Jersey, have invented certain 'new and useful.Improvements in ventilators, of which the vfollowing is a specification,reference' being had therein to theaocompanying drawings,

This invention relates to improvements in ventilators, and has for itsprimary obj ect the provision of a device of thisfcharacter which willbe adapted to fit windows as ordinarily installed and of various sizesand also ISy f tical embodiment of the invention comprises I besusceptible of ei'lcient use either in fixed v moving With the foregoingobject in view a prac-i a supporting-frame, a casing carried thereby;4preferably arrangedonv the inside 'of the frame and having anexit-opening at its top;

" oppositely disposed inlet openings facing outwardlyfrom the frame, anda balanced 'horizontallyfdisposed movable delector in' the casingbeneath the exit-o ening thereof;

. and intermediate the opposite y-dispesed in let-openings, saiddeflector being balanced, s0'

as'to be highly sensitive to any gust or per-| ceptible air-current' andto close toward the incoming air to prevent direct escape thereofthrough Ythe exit-opening 0n the interior of the device, such movementcausing said air to pass through the casing and out of the op positeopening, therebycreating a suction, or

opposite draft from theroomor `car`- Under normal conditions-as, forinstance, when a "caris at a standstill, and in thexcaseof a house whenthere is no perceptible air-'current without-'the deflector will assume-its normal or trueliorizontal position to permit a lightl comfortableingress of air through,

both ofthe inlet-openings into the casing and -'thence throughtheexit-opening of said casing into the room or car'. i

Th foregoing, as Well as other-novel de-v l t'ail'sin the constructionand arrangement of the partsof the ventilator, will be apparent from thedetailed description hereinafter given when read in connection with theaccompanying drawings, forming part hereof,

wherein a vconvenient embodiment of the in-- vention is illustrated.

In the drawings, Figure lis a perspective Referring more speciiically tothe draw-"y ings, wherein like reference characters refer tocorresponding parts in the several views,- A designates a convenientsupporting-frame,

which maybe readily formed of wood or any other material suitable to theconditions :ati tendin the use for which. itis provided, said frameaving an extensible section B at one 'end adjustable through the mediumof a slota'n'd-,scr'ew connection C, whereby the frame may be adjustedwith respect to its length toH iit window-casings of various widths agiven range;

On the inside 0f the frame I mount a'ca'sing D, preferably formedoff'm'etal o f-a style and color to agree with the surrondings attendingits use, tlie'ends of said .casing inwardly toward each other, asat E.Thevtop wall of this casing is provided withan openingto aff' ford readypassage of air therethrough intofa room or the like,`sa id opening beingscreened,`

as represented at F.

G Gr are box-likeinlets projecting outwardly slightly beyond theouter'surface of ner ends with Opposite ends of the casing, theseinlets'being also preferably directly opposite the inclined wal s of thecasing, wherey the air admitted through the-inlet willige deflectedinwardly and longitudinally-fof' casing by said inclined 'walls l`The,'uter? lthe frame A and communicating at their inare screened, as at H,and are each 'inclined inwardly and toward the end of the device atwhich it is located, whereby theyv face'iiifopposite directions, asclearly shownpin Figs. 3` and 4. f

Within the casing, beneath the o ening constituting' the eXit therefromand a so intermediate the inlet-openings G G', a pivoted ICO deiiector Iis supported upon the pivot J, the pivot being centrally arranged andthe opposite ends of the deiiector being balanced, whereby its normalposition is in a horizontal plane and longitudinally of the casing. As

shown, this deilector is of somewhat angular formation, the endsthereofbeing turned upwardly toward the top of the casing for a purpose as willpresently appear.

The position of the arts being assumed to be that last above de ed, whenthere is no perceptible air-current on the outside both of the inlets GrG may admit to an agreeable extent air into the casing, from whichlatter it Will escape through Vits exit-opening into the room or car.`When, however, there is a suddengust of wind or a perceptible current.of air Without `the device, `the same will enter the `inlet-opening GorGr, facing in the direction opposite to the direction of flow of theair, and owing to the impingment of the air upon the nearest upturnedend of the deiiector the same will be 'rocked into the positionindicated in Fig, whereby to .close the exit-opening of the casingagainst said aircurrent, thereby compelling the same to pass on throughthe `casing and out of the opposite opening 'G or G', as the case maybe, the latter under these conditions servingvas an .exitopening, .as isobvious, with the resultant effect that a vacuum for outdraft from theroom through the casing is secured. Of course when the ventilator isemployed on moving vehicles, such as railway passengercars, thedeflector .occupies one of its shifted positions continuously during themovement of the train and the device operates as an eX- h-aust. However,when the train is at a standstill the operation is just the same as whenthe ventilator is used ina xed structure.

`It .is to be understood that the invention `is :susceptible of otherembodiments than that disclosed herein and also .that the form-of deviceshown may bealtered `and changed without departing `from the spiritofthe invention.

Having thus described the invention, what is claimed as new, .anddesired to be secured by Letters Patent, is-

l, In `a ventilator of the character dei scribed, `a casing havingclosed ends and a pair of oppositely-disposed inlet openings, and an.exit-opening, the ends of said casing being inclined toward theoutlet-opening, and the inlet-openings being opposite and at an angle tosaid inclined ends whereby to delect the air inwardly, and a movabledelector in said casing intermediate said inletopenings.
